Glass feeder

Glass feeder

The patent-pending torque-feeder design is based on two servo-axes:  The plunger can be moved vertically up and down, the second servo axis performs the rotation.


  • Technical data:
  • - Standard dimensions: Ø 550 x H 1.820 mm
  • - Torque drive feeder stroke: Mmax 89.1 Nm
  • - Servomotor needle rotation: Mmax 1.6 Nm
  • - Production speed: 60 1/min
  • - Max. needle stroke: 1.000 mm
  • - Traversing speed: 533 mm/sec
  • - Weight: 200 kg

The advantages of glass feeder

  • No gears or other wear-prone, mechanical elements are required for the lifting axis
  • Compact size
  • No reactive forces in the entire drive train
  • The nut of the ball screw is directly connected to the rotor of the motor and thus completely free of play
  • The encoder system is also directly connected to the rotor and the nut of the ball screw
  • The water-cooled spindle of the ball screw is led
  • through the motor, thereby supplying internal
  • motor cooling plus water cooling of the outer
  • curved surface
  • All mechanical parts are water-cooled
  • Automatic central lubrication
  • The rotary axis supports various operating modes such as synchronous and asynchronous operation or constant speed
  • For changing, the plunger can be taken completely out of the channel area using the feeder mechanism

Platinum gutters:

The product of the continuous development in the production of Zwiesel crystal glass is a platinum gutter system, which ensures very short reaction times to glass transition temperature. The advantage over common ceramic systems lies in stable temperature control, even under changing environmental conditions and throughputs.

The benefits of platinum gutters

  • Direct heating
  • Very short response times
  • Four heating zones
  • Meets the highest demands on glass quality
  • Made in Germany
